NatuRose Haematococcus algae meal is a natural source of astaxanthin derived from a unique strain of microalgae, Haematococcus pluvialis. NatuRose is spray dried and formulated into a fine dark red powder and is currently used worldwide as a coloration and nutrition source for numerous aquatic species. It has been successfully used for pigmenting marine shrimp, rainbow trout, salmon, sea bream, and ornamental fish, koi, and poultry. Enrichment of rotifers, Artemia, and daphnia is achieved by direct feeding of NatuRose in tanks and are also used as a superior larval feed.
Usage:
The majority of the NatuRose carotenoid fraction is astaxanthin, which imparts the red hue to aquatic animals. Astaxanthin is sensitive to light, heat, and oxygen so precautions should be taken to protect this carotenoid from oxidation. NatuRose is manufactured with 0.3% ethoxyquin to enhance the stability of the carotenoids, and is shipped in sealed, airtight pouches. The product should be kept at room temperature (72F or 22C) or cooler to allow maximum stability during storage.
When feeds are to be manufactured, a measured amount of NatuRose is added smimlar to using a premix. Good distribution within the total feed will ensure consistency within the final feed. Depending on the application, NatuRose containing 2% astaxanthin (20,000 ppm) is incorporated into feeds at a final concentration of 2.5 kg to 5 kg per metric ton of feed (50-100 ppm final astaxanthin).
Pelleting of feeds offers the optional conditions of low heat exposure; losses of astaxanthin generally range from 1-4%. The extrusion process popular with many feed manufacturers is also compatible with NatuRose. Losses generally range from 4-12%. NatuRose is very stable in oils as top-coating of pellets with a NatuRose/oil mixture has also proven successful.
Fresh feeds made in a "batch" fashion by aquaculturists raising tropical fish or shrimp broodstock have reported improved growth, survival and pigmentation as no heat is required during the feed processing. NatuRose can be blended directly into these feeds and will offer excellent stability while frozen.
NatuRose "natural astaxanthin" is not being fed to marine shrimp, koi, rainbow trout, sea bream, salmon, crawfish, abalone, goldfish, macrobrachium, and a variety of marine and freshwater ornamental fish species.
